Answer 1

1. 9/10 + 7/8 = 71/40 (or 1.775) so I'd say 2

2. 9/50 + 7/15 = 97/150 (or 0.64667...) so I'd say 1/2

3. is this 2/8 / 9 or 2 / 8/9 please let me know

4. is this 8/12 / 31 or 8 / 12/31 :)

5. is this 15/2 / 15 or 15 / 2/15

Please let me know the second halves of 3 through 5 as well! :)
